I just adopted a 6 month old black lab shepard mix. In a few months I don't think he will have any problem getting in an out of the FJ comfortably, but right now he is a skittish adolescent who has some growing to do. Do you have any advice on how you keep your dogs comfortable in your big truck? Do you use a seat belt harness, do you put the seats down, do you use a bed? I have never had my own dog before and have never had a dog in my FJ so I'm not sure how to keep him happy. Any advice would be appreciated.
